The following images, photographs, illustrations, videos and media or "Structural health monitoring at Taizhou Bridge, China" include visual details and information about this product or case study.

An 18-gap modular joint of the Taizhou Bridge

A modular expansion joint on the Taizhou Bridge, viewed from below

Fault simulation on a large modular expansion joint of the Taizhou Bridge. One of the steel stirrups, which connect the joint's surface beams to the support bars beneath with a pre-stressed sliding connection (consisting of a sliding bearing above the support bar and a sliding spring below), has been temporarily removed, enabling the vibrations experienced by this "damaged" expansion joint to be recorded

Example of recorded data (overall movements)

Correlation between displacements of a particular lamella beam (on the surface of an expansion joint) and the overall movements of the bridge: A 45° inclination of the correlation graph would indicate that these values are equal
